   <span class="function"><strong>proc_close()</strong></span> is similar to <span class="function"><a href="function.pclose.html" class="function">pclose()</a></span>
   except that it only works on processes opened by
   <span class="function"><a href="function.proc-open.html" class="function">proc_open()</a></span>.
   <span class="function"><strong>proc_close()</strong></span> waits for the process to terminate, and
   returns its exit code.  If you have open pipes to that process, you
   should <span class="function"><a href="function.fclose.html" class="function">fclose()</a></span> them prior to calling this function in
   order to avoid a deadlock - the child process may not be able to exit
   while the pipes are open.
